I will add something from myself in case of FS-ZE camshaft in FS mazda engine. I bought that camshaft from Corksport about 6 months ago. I have put it with completly modified cylinder head, and some other things like nology spark plug wires, and outlaw engineering spacer kit. First dyno run (before any mods - except exhaust and intake
- that was done about 2 years ago) and I had 118BHP and 154NM of torque.
Then we've measured my car after mod. head and FS-ZE intake cam inside. We've recived 132BHP and 161NM of torque on wheels.
After ECU tuned whit ECU Master final result was 138BHP and 166NM.
Car has been idling very bad
(but that is characteristic for high lift cams). The power band was disadvantageous too. HP and torque peak was better only after 5500 rpm. Below this range car was a lot weaker compare to the stock cam setup. Acceleration from 0-100 - the same (maby a bit worse whit low-rev start) as it is now - about 9s.
Whit full exhaust and intake but whitout head mods, and ECU upgrade I have been making times around 9,7s. I couldn't drive a car whit that kind of power band every day. It was very annoying. I had to rev it over 5000rpm on every gear to get it moves properly - there was no acceleration under 2500 rpm on 5th gear
Now I'm driving whit: full exhaust (with 4-1 header, and hi-flow kat), intake with BMC airbox, modified cylinder head and ECU upgraded whit "ECU Master" piggy back. Whit this setup I have 125 BHP and 170NM of tourqe. Compare to FS-ZE camshaft average power
is now better for about 2HP
, and average torque
is better for about
Look at these dyno runs and decide if FS-ZE is worth buying.
These runs have been done whit mod. cylinder head, exhaust and intake.
The only thing that is different, is the FS-ZE camshaft !!
Stock cam vs. FS-ZE cam:
As you can see: stock cam is better in green section, FS-ZE camshaft is better in red section.
On -ZE cam, car has got wrong AFR on low revs (too much fuel - and not enought air) and also on high revs (too much air - not enought fuel). Results propably would be better whit biger fuel pump and injectors installed. And whitout rev limiter of course
Stock cam is perfect for normal driving - properly power gain across all range of revs providing smooth ride. FS-ZE camshaft is better than for racnig, when you're reving your engine [fizze] ing hard. Or it can be good for a street car, of course if you like high power on very high revs. If you don't - stay with stock cam
